none3noThe aim of this paper is to explore forecast passenger demand techniques in long-term and short-term perspectives at regional airports. The analysis has been applied at Bologna Airport, a large regional airport in Italy with a balanced mix of low cost traffic and conventional airline traffic. In the long-term perspective, a time series model is applied to forecast a significant growth of passenger volumes at the airport in the period 2016-2026. In the short-term perspective, time-of-week passenger demand is estimated using two non-parametric techniques: local regression (LOESS) and a simple method of averaging observations. Adopting cross validation method to estimate the accuracy of the estimates, the simple averaging method a...
